Studies shed light on hand hygiene knowledge and infection risk in hospitals and elementary schools

05.08.2011
Increased hand hygiene knowledge positively correlates with a decreased risk of transmitting infection among both healthcare workers (HCW) and elementary school children, according to two studies published in the August issue of the American Journal of Infection Control (AJIC), the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology.

In the first study, conducted by Anne McLaughlin, Ph.D., Assistant Professor of Psychology at North Carolina State University, 71 nurses, infection preventionists and hospital environmental services managers participated in a national survey gauging hand hygiene knowledge and beliefs.

Each HCW assessed 16 real-life simulations designed to test their perceived risk of infection, based on their level of hygiene knowledge as well as their internal health locus of control (internal-HLC)—a measurement of how much influence they perceive themselves as having over controlling the spread of infection.

The study found that across all knowledge- and HLC-levels, HCWs perceived surfaces as safer to touch than patient skin, in spite of research that has proven touching one contaminated surface (known as a fomite) can spread bacteria to up to the next seven surfaces touched.

"Despite the dangers that fomites present, this knowledge may not be common enough among HCWs for them to understand the level of risk when touching surfaces and then touching patients," say the authors.

Hand Hygiene is "Elementary"

Hand washing programs among school children may have a lasting effect in reducing school absences, according to a study published in the August issue of AJIC. A three-month targeted intervention to reduce student absenteeism through increased hand hygiene was conducted in 2008. Infection preventionist Inge Nandrup-Bus, RN, directed the study at two elementary schools in Denmark and compared her results to a similar study she performed in 2007—the only significant change being that for the second trial, the Intervention School (IS) and the Control School (CS) were reversed.

At the IS, 324 pupils ages 5-14 years were each given one lesson in hand disinfection theory and practice and directed to disinfect their hands using ethanol gel three times throughout the school day. Over the three months of the intervention, this measure resulted in a 66 percent decrease in pupils with four or more days of absence and a 20 percent increase in children with zero absences over the 2007 data from the same school.

In the CS, however, which had been the intervention school the prior year in hand washing, no significant changes were noted between 2007 and 2008—a result that strongly suggests that even with low participation rates (20% in 2007 and 21% in 2008) and the passage of time, merely increasing hand hygiene education can have a long-term, significant impact on the spread of infection.

"Regular training in HW (hand washing) and HD (hand disinfection) would be a simple, low cost action with very significant impact on reducing infectious illness absence periods among pupils," stated the author.

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
